Research on hybrid optimization and deep learning modeling method in the performance seeking control

Abstract: A novel performance seeking control method based on hybrid optimization algorithm and deep learning modeling method is proposed to get a better engine performance. The deep learning modeling method, deep neural network, which has strong representation capability and can deal with big training data, is adopted to establish an on-board engine model. A hybrid optimization algorithm—genetic algorithm particle swarm optimization–feasible sequential quadratic programming—is proposed and applied to performance seekin… Show more

“…As for the accuracy of the on-board model, it not only influences the optimization results but may also bring the engine to unsatisfied constraints. 9,10 At present, most scholars use the piecewise linear model (PLM) or component level model (CLM) as the on-board model for PSC. [11][12][13][14][15][16][17] The PLM has good realtime performance.…”

“…5,6 However, the control error is inevitably existing if the engine model is linearized due to the strong nonlinear characteristic of engine. Therefore, some scholars proposed a series of PSC optimization algorithms, [7][8][9][10][11][12][13][14][15][16][17] such as MAPS (Model-Assisted Pattern Search), 18 SQP (Sequential Quadratic Programming), 19,20 FSQP, 7 PSMA (Particle Self-Migrating Algorithm), 8,9 GA (Genetic Algorithm), 10 PSO (particle swarm optimization), 11 IA (Interval Analysis). 12 During these algorithms, the probability-based algorithms, such as GA, PSO, make engine get better engine performance.…”
